ens-HEATER.

To all whom t may concern.' f

Be it known that I, GEORGE E. SHARPE, a citizen of the United States,residing at Steubenville, Lin the county of Jefferson and State of Ohio,have invented certain new and useful Improvements in Gras-Heaters, ofwhich the following is a specification.

This invention relates to gas heaters, and has for its object theprovision of an ineX pensive device which may be set inan openlire-place or used at any point in a room as a stove andin which the"fumes and currents risingy from the gas yburner will be causedtocirculate `in a path which willreturn them to a point immediatelyadjacent and above the burner where they? will be mingled with the flameand, consequently,

all particlespof carbon and similar matter consumed with an'economicaliiowof gas.

The invention also seeks to improve the yconstruction of the heater tothe end that the parts of the same may be readilyassembled and thedevice as a whole given an `ornamental* appearance,` the odorsordinarily `attendant upon the use of gas'heaters being overcome and theair within the room quickly raised to the desired temperature.

A further object of the invention is to provide a structure which may beconnected A to a flue to carry off the products of combustion andtoalsoprovidemeans whereby the mantel willbeproteoted whennthe device islocatedl ina fire-place. y n The invention is fully illustrated in theaccompanying drawings and consists in certain novel features which willbe rst fully described and then more particularly pointed out in theclaims following the description. In the drawings: Figure l is a frontele vation, partly broken away, of a'heater embodying my presentimprovements; Fig. V2 is a vertical section of the same taken on theline 2--2 of Fig. l; Fig. 3 is a detail perspective view of a -portionof the shield which is interposed between the water'box or pan and theburner; and Fig. 4 is a detached perspective view of a portion of theupper damper orupper hood protector.

`Inl carrying outmy invention, I employ a housing l which is preferablyof sheet metal and is cfa size to lit within a livreplace, as willbereadilyl understood, the said housing being of any desired dimensionsand comprising a back, sides and a top, as will Specication of LettersPatent.A Y Patented Sept. 28, 1915.

be readily understood. I also employ Va front, which may be of anypreferredvdesign,- and is preferably of cast metalv so as to possess theVnecessary strength and durability. f

In the drawings, I have shown the front' as comprising an upper'section2 having a hood 3 projecting forwardly and down-y wardly and secured tothe top of the houslng by suitable bolts inserted through the iangey tof the housing and the section 2 of f rfi-an srarns rarfnnr orrren.

the front, as will be readily understood."

Belowfthe saidrtop section 2 are side mem-4 bers 5 which yare secured bysuitable bolts to side iianges 6 of the housing, and rbetween the saidside Vmembers 5 below the hood SisV isecured a screen or grille 6 which,in the illustrated form, comprises Va plate having vertical slots 7 andalso provided with a downwardly and outwardly projecting hood 8 belowthe said slots. Between the lower ends of the side members 5, I securethelower screen or grille 9 which, in the present drawings, is/shown asVsimilar in appearance and constructionto the upper screen or grille 6but which may, of course, be of any other de-` sign which may provideopenings through which cold air may pass into the housing;v

The space between the hood 8 Aand the screen or Vgrille 9 .is open, asclearly shown in the drawings, and within the housing,A

back of the said open space, is a deflector`n plate 10 which ispreferably constructed of sheet metal for the sake of economy andlightness and is provided with side iianges, indicated 4at '11, throughwhich suitable bolts are inserted to secure the same to the sides of thehousing. The front face of this delector plate is covered with asbestos,as

shown at 12, and near the lower end of the said plate is a passage 13for heated cur-` rents, which passage may be a single slot extendingacross the width of the plate or a series of alined short slots orperforations. The upper end of the deflector plate is secured to aninner hood 14 which is suitably:

shaped to t within and constitute a lining for the` hood 8 and alsoprovide a chamber 15, in which the heat may collect before p passingthrough Aa vertical flue or a series of fiues 16j into a drum 17 whichislocated back of the upper end or edge of the screenA or grille 6. Thedrum 17 is supported by the upper ends of the fines 16 and is preferablyconstructed of sheet metal plates hav- 'y k'ing theiry meeting'edgesinterlocked in any desired mannerfas indicated at v18,V the saidinterlocking edges being brazedv or otherwise intimately connected sothat tight joints will be provided. A short flue 19 leads from the backof the drum 17 through the back plate ofthe housing l, and this flue maybe corinectedwithachimney or other conduit* to carry off the products/ofcombustion, if,

- desired. It is not necessary, however, to so -vconnectithis flue,and-ordinarily l close the outer end thereof byvlacap 2U. HIn rear 0fthel flues 16, I provide longer flues' 2 1 whichy openv at their upperends into the druin 17 and extend downwardly from the said drumV f. inrear of the deflector plate and have H theirlowery ends opening into theboxor handle Inayjproject Vthrough the grille v921 lor may beotherwiseconveniently located.

will be readily understoodthat the heated gas currents flowing from thebox 22 will vbe turned upwardly by this lipv 25 so that instead offlowing across the burner 23 they will risevtherefrom and be feddirectly into the flame.

A panter water boX 27 is secured the rear side of the grille 9 at theupper edge y [which bolts may be inserted tov secure it to the sidesofthe housing between Athe same andthe ends of the water boX, the ends ofthe said shield being suitably shaped to fit Y closely to the sides ofthe deflector plate and vto the ends of the pan, as will be readilyvunderstood. The said shield isfalsopro.- videdwitha depending flange 30which enters the waterl box, as shown clearly in Fig. 2, and therebycovers therear VVwall of the same.A Copper plates 311nay. also be placedYagainst the sideportions of the deflector so as to cover the same andthereby add to. the ornamental heater. i c y The" upper grille vG "is soVshaped or arranged as to provide anr open space 32be-v tween its'upperedge and the loweredge of the hood 3 throughwhich the heated air mayvescape into 4the room above the Adrum 17,Y and to protect themantelwhen the device is located VVVinY (a, fireplace If-provide Vtheshield or damper 33 which consists of av fiat sheet metalp'plate`slidably supported upon guides 34 secured tofthe sides ofthe housing lnear1 the 4upper end thereof, the platev 33V being' provided withlongitudinal flanges or ribs 35 at its ends to fit over the saidpguides34, as shown in .Fi-g. 1.V It will also be noted@C from said-,figurethat the` grille 6 Vispro-A vided. with small notches 3 6 at its ends tofacilitate the entrance of the damper lorVv shield into position, andthefront edge of Y the said shield is turned upwardly,.as shown appearanceof vthe at 37, and equipped with-,a handle 3 8 so thatit may be readilymanipulatedand will be limited in itsinward movement by vtheisaidupeturned rflange engaging the Vfront facey of the lowerl edger ofl thevhood 3. To.V guardA againsty buckling of the said plate 33 at the endsof the same, I provide the keeper guides l 39 .which consistuof sheetmetal Vplates secured tothe sides of thephousing and hav ing. theirlower ends projected inwardlyy to extend over `theends ofthe damperplate, as clearly'shown.r l i f t-is thought the-use and advantages ofmay improved device will be readily under stood from the4 foregoingdescription takenA in connection with the accompany-ing dirawmanner andthe flame willsextend", upwardly in front of the dellector plate, as isevident.4

.Theheat thrownout directly by thel flame will'be reflected .intol the4room through the open space between the lower grille and the ilowerhood, while the fumes of the-gasl willr pass upy through theflues 16into the drum 17. ,From the drum 17, the gas fumes and ings.y Thegas isignited in the*V ordinary the, productsK4 of `combustion wfil-lvdescendUthrough the iues 21 into the `box 22 and thence escape through theopening or open-vr ings 13 to the space above theburner.v The heat.Yfrom the flame will, of course, create an upward flow of aircurrents,and the lip 25 will prevent the currents from the box 22rpassing across the burnerV and. will turn. the same upwardly thereby`actingrin conjunction with the natural suction created by the fla-me.The currents from the Haine will' thus be given circulation from the Yburner andback to the saine so that the odorfgiving particles will beconsumedand a small supply ofgas will serve to. quickly n bring thetemperature of the room to the desired degree. will pass through thelower grille or screen under the detiector plate Vand then rise withinthe housing around the flues 16 and 21 and the drum 17 and finallyescape through the upper screen and over the upper edge of the same. Ifthe heater be located in a lire-place, the shield or damper 33 may bedrawn forward so that it will extend out beyond the hood 3 and will.thus serve to prevent the heated air from iiowing directly over thefront face of the said hood 3 and against the mantel. They will be,moreover, thrown out into the room and toward the fioor of the same sothat the room will be quickly heated.

it will be readily noted that the device effects twocounter-circulations, the air of the room being caused to rise back ofthe deiiector plate and around the fines and drum and then escaping intothe room from the upper portion of the heater, while the products ofcombustion and theA gaseous currents will be caused to rise through theiues 16 and the drum and then descend through the iues 21 and return toa point above the burner. rlhe drum and the flues, as well as the box 22being constructed of sheet metal, will be quickly heated so that thefresh air currents rising around the samet will be quickly raised intemperature. rllhe drum 17 is, of course, spaced from the back of thehousing so as to facilitate the circulation of the fresh air currents,`and it will be noted that the drum, the fines', the lower box 22,together with the defiector plate and the inner hood and heat chamber15, will form one rigid structure so that the parts may be readilyassembled when setting up the apparatus.

The provision of the water boxor pan 27 provides for the supply of avapor above the burner to replenish rthe consumed particles in thegaseous currents, and the shield y28 between the pan and the burner willprevent the liooding of the burner when the supply of water is beingreplenished and will also impart an ornamental appearance to the devicewhich will perceptibly increase its attractiveness. Moreover, thisshield 28 and the side plates 21 beingof burnished copper will serve asrei ectors to throw heat out into the room and as the shield restsdirectly onV the burner close to the openings therein, it will becomeheated and, consequently, aid in the vaporization of the water in thebox 27.
